This book explores the use of biomass as an energy source and its application in energy conversion technologies. Focusing on the challenges of, and technologies related to, biomass conversion, the book is divided into three parts. The first part underlines the fundamental concepts that form the basis of biomass production, its feasibility valuation, and its potential utilization. This part does not consider only how biomass is generated, but also methods of assessment. The second part focuses on the clarification of central concepts of the biorefinery processes. After a preliminary introduction with industrial examples, common issues of biochemical reaction engineering applications are analysed in detail. The theory explained in this part demonstrates that the chemical kinetics are the core focus in modelling biological processes such as growth, decay, product formation and feedstock consumption. This part continues with the theory of biofuels production, including biogas, bioethanol, biodiesel and Fischer-Tropsch synthesis of hydrocarbons. The third part of this book gives detailed explanations of preliminary notions related to the theory of thermodynamics. This theory will assist the reader when taking into account the concepts treated in the previous two parts of the book. Several detailed derivations are given to give the reader a full understanding of the arguments at hand. This part also gives literature data on the main properties of some biomass feedstock. Fundamentals of Biofuels Engineering and Technology will be of interest not only to academics and researchers working in this field but also to graduate students and energy professionals seeking to expand their knowledge of this increasingly important area.
Nuclear magnetic resonance (NMR) is an analytical tool used by
chemists and physicists to study the structure and dynamics of
molecules. In recent years, no other technique has grown to such
importance as NMR spectroscopy. It is used in all branches of
science where precise structural determination is required and
where the nature of interactions and reactions in solution is being
studied.
This book offers a pragmatic guide to navigating through the complex maze of EPR/ESR spectroscopy fundamentals, techniques, and applications. Written for the scientist who is new to EPR spectroscopy, the editors have prepared a volume that de-mystifies the basic fundamentals without weighting readers down with detailed physics and mathematics, and then presents clear approaches in specific application areas. The first part presents basic fundamentals and advantages of electron paramagnetic resonance spectrscopy. The second part explores severalapplication areas including chemistry, biology, medicine, materials and geology. A frequently-asked-questions sections focuses on practicalquestions, such as the size of sample, etc. It's an ideal, hands-on reference for chemists and researchers in the pharmaceutical and materials (semiconductor) industries who are looking for a basic introduction to EPR spectroscopy.

The knowledge base of chromatography continued to expand throughout
the 1990s owing to its many applications to problems of
contemporary interest in industry, life and environmental sciences.
Organizing this information into a single text for a diverse group
of scientists has become increasingly difficult. The present book
stemmed from the desire to revise Chromatography Today, written by
the same author with Salwa K. Poole, and published in 1991. This
title is considered to be one of the definitive texts on
chromatography. It was soon realized however, that a simple
revision would not provide the desired result of a contemporary
picture of the practice of chromatography at the turn of the
century. The only workable solution was to start afresh,
maintaining the same general philosophy and concept for
Chromatography Today where possible, while creating essentially a
new book.

This book reports new findings in the fields of nonlinear optics, quantum optics and optical microscopy. It presents the first experimental device able to transform an input Gaussian beam into a non-diffracting Bessel-like beam. The modulation mechanism, i.e. electro-optic effect, allows the device to be fast, miniaturizable and integrable into solid state arrays. Also presented is an extensive study of the superposition of Bessel beams and their propagation in turbid media, with the aim of realizing field that is both localized and non-diffracting. These findings have been implemented in a light-sheet microscope to improve the optical sectioning. From a more theoretical point of view this work also tackles the problem of whether and how a single particle is able to entangle two distant systems. The results obtained introduce fundamental limitations on the use of linear optics for quantum technology. Other chapters are dedicated to a number of experiments carried out on disordered ferroelectrics including negative intrinsic mass dynamics, ferroelectric supercrystals, rogue wave dynamics driven by enhanced disorder and first evidence of spatial optical turbulence.
This book studies the dynamics of fundamental collective excitations in quantum materials, focusing on the use of state-of-the-art ultrafast broadband optical spectroscopy. Collective behaviour in solids lies at the origin of several cooperative phenomena that can lead to profound transformations, instabilities and phase transitions. Revealing the dynamics of collective excitations is a topic of pivotal importance in contemporary condensed matter physics, as it provides information on the strength and spatial distribution of interactions and correlation. The experimental framework explored in this book relies on setting a material out-of-equilibrium by an ultrashort laser pulse and monitoring the photo-induced changes in its optical properties over a broad spectral region in the visible or deep-ultraviolet. Collective excitations (e.g. plasmons, excitons, phonons...) emerge either in the frequency domain as spectral features across the probed range, or in the time domain as coherent modes triggered by the pump pulse. Mapping the temporal evolution of these collective excitations provides access to the hierarchy of low-energy phenomena occurring in the solid during its path towards thermodynamic equilibrium. This methodology is used to investigate a number of strongly interacting and correlated materials with an increasing degree of internal complexity beyond conventional band theory.

Analytical pyrolysis is one of the many tools utilized for the study of natural organic polymers. This books describes in three parts the methodology of analytical pyrolysis, the results of pyrolysis for a variety of biopolymers, and several practical applications of analytical pyrolysis on natural organic polymers and their composite materials. Analytical pyrolysis methodology covers two distinct subjects, the instrumentation used for pyrolysis and the analytical methods that are applied for the analysis of the pyrolysis products. A variety of pyrolytic techniques and of analytical instruments commonly coupled with pyrolysis devices are given. The description of the results of pyrolysis for biopolymers and some chemically modified natural organic polymers is the core of the book. The main pyrolysis products of numerous compounds as well as the proposed mechanisms for their pyrolysis are described. In this part an attempt is made to present as much as possible the chemistry of the pyrolytic process of natural organic polymers. The applications of analytical pyrolysis include topics such as polymer detection used for example in forensic science, structure elucidation of specific polymers, and identification of small molecules present in polymers (anti-oxidants, plasticizers, etc.). Also, the degradation during heating is a subject of major interest in many practical applications regarding the physical properties of polymers. The applications to composite polymeric materials are in the fields of classification of microorganisms, study of a variety of biological samples, study of fossil materials, etc. Analytical pyrolysis can also be used for obtaining information on the burning areagenerate pyrolysates that have complex compositions. Their analysis is important in connection with health issues, environmental problems, and taste of food and cigarettes. Features of this book: - Presents analytical pyrolysis as a uniform subject and not as a conglomerate of scientific papers. - Puts together in an organized manner a large volume of available information in this specific field. - Provides original results which address subjects with relatively scarce information in literature. - Gives original views on subjects such as the parallel between the pyrolytic process and the ion fragmentation in mass spectrometry. - Includes the role of pyrolysis in the burning process.
